There are several potential causes for a vehicle that will not start or crank over. Some common causes include:
Dead battery: If the battery is dead or weak, it may not have enough power to crank the engine.
Failed starter motor: The starter motor may have failed and is no longer able to crank the engine.
Failed ignition switch: If the ignition switch is not functioning properly, it may not send the necessary power to the starter motor to crank the engine.
Failed fuel pump: If the fuel pump is not functioning, the engine may not receive enough fuel to start.
Failed fuel pump relay: If the fuel pump relay is not functioning properly, it may prevent the fuel pump from running and the engine from starting.
Failed fuel filter: A clogged or failed fuel filter can prevent the engine from receiving enough fuel to start.
Failed spark plugs or ignition wires: If the spark plugs or ignition wires are not functioning properly, the engine may not receive the necessary spark to start.
